Large Salmon Arab Butterfly

Of the nearly 19,000 butterfly species in the world, only 63 occur in Egypt. And this beauty – a Large Salmon Arab (Colotis fausta) – has been fluttering about my garden lately!

We are lucky here in South Sinai, as the mountainous region is one of the hotspots of butterfly diversity in Egypt, home to 2/3 of the butterflies found in Egypt. The Salmon Arab is a member of the Pieridae family of butterflies, or Whites, as they are commonly called. Like most butterflies, they go through a 4-stage metamorphosis: egg, larva (caterpillar), pupa (chrysalis), and adult. The eggs are laid on and the caterpillar feed on the leaves of caper bushes (Capparis sp.), which is why I find these butterflies in my garden and where you’ll usually spot them in the wadis. The caterpillars are light green, hairy, and have a pale-colored stripe through their body.

The larva continue to eat, grow, and molt (shed their skins) until they are ready to form their chrysalis (a hard skin) and start to pupate. The chrysalis is attached, usually to a leaf, by silk threads.

After about a week, the adult butterfly emerges.

The upperside of the wings are a salmon-pink to an orange-yellow color and the forewings have dark scales and black spots along the edges. In the dry season, they are smaller and lighter-colored. You can find these butterflies in flight between April and November.

As a curious nature-lover as well as a teacher, I will occasionally raise caterpillars indoors to learn more about them. Check out the proboscis (sucking mouth part) on the newly-emerged butterfly below!

Although the weather is getting a bit too hot to be wandering through wadis these days, you might just spot these butterflies near the caper bushes around town!
